Description
Technical Field
The utility model belongs to the technical field of the buggy sieve, concretely relates to novel sealed lid of buggy sieve.
Background
The pulverized coal sieve is mainly used for a blast furnace coal injection system, and due to the special technological environment of the pulverized coal sieve, the inside of the pulverized coal sieve is in a negative pressure state, so that the pulverized coal sieve has higher requirements on the sealing performance of the sieve. The buggy sieve mainly acts on the edulcoration, material such as braided bag promptly, there are material such as fibre to block up the sieve mesh in the material, so on-the-spot buggy sieve board 1 week usually need clear up 2 times with the steel brush, the sealed lid of usual buggy sieve seals for steel sheet pressure equipment sealing strip, sealing performance does not have the problem, but there is negative pressure state usually in the buggy sieve screen body, adopt this kind of structure scene of steel sheet pressure sealing strip to open and cover again, because the sealed strip of negative pressure state can be inhaled inside the sieve body, it is very inconvenient to cause the sealed lid of on-the-spot installation, the sealing strip of not flattening well, waste time and energy, the manual work is removed the maintenance degree of difficulty very big, often several workman will be long time together and can flatten sealing strip.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect among the prior art, and provide a novel buggy sieve sealed lid that structural design is simple reasonable, easy dismounting, labour saving and time saving and leakproofness are good.
The purpose of the utility model is realized like this: including the lid, be equipped with a plurality of bolt locating hole on the lid frame, be equipped with the bolt in the bolt locating hole, be equipped with the nut between bolt and the lid upper surface, be equipped with the pull clamp plate in the frame of lid, the lower surface of pull clamp plate is equipped with the insulation board.
Preferably, the bolt is a T-shaped bolt.
Preferably, the nut is a spot welding nut.
Preferably, the insulating plate is made of insulating paper.
The utility model discloses an insulation board and pull clamp plate seal up, just can accomplish alone and dismantle the cleaning work, have that structural design is simple reasonable, easy dismounting, labour saving and time saving and the good advantage of leakproofness.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, in which like reference numerals refer to like parts in the drawings. For the sake of simplicity, only the parts related to the utility model are schematically shown in the drawings, and they do not represent the actual structure as a product.
As shown in fig. 1, 2 and 3, the utility model relates to a novel sealed lid of pulverized coal sieve, including lid 1, be equipped with a plurality of bolt locating hole 2 on the 1 frame of lid, be equipped with bolt 3 in the bolt locating hole 2, be equipped with nut 4 between bolt 3 and the 1 upper surface of lid, be equipped with pull clamp plate 5 in the frame of lid 1, the lower surface of pull clamp plate 5 is equipped with insulation board 6.
Further, bolt 3 be T type bolt, T type bolt convenient to detach, rotate T type bolt and can dismantle fast when dismantling.
Further, the nut 4 is a spot welding nut.
Furthermore, the insulating plate 6 is made of insulating paper.
The utility model discloses open this sealed lid when the on-the-spot clearance sieve, need not any instrument, manually loosen T shape bolt alone, take pull clamp plate 5 out, take out insulation board 6 and can clear up the sieve. The insulating plate 6 serves as a seal.
The utility model discloses the structure is though simple, nevertheless clears up very practicality to the buggy sieve, and is also very convenient, and work that originally several people were accomplished just can be accomplished alone now, and labour saving and time saving economizes the manual work, and it is very convenient to change and clear up, has saved a lot of manpower and materials for the enterprise.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected," "connecting," and the like are to be construed broadly, and may be, for example, fixedly connected, integrally connected, or detachably connected; or communication between the interior of the two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation. The above detailed description is only specific to the feasible embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments, modifications and alterations without departing from the spirit of the present invention should be included in the scope of the present invention.
